Impact of grinding process on the mechanical behavior of CVI-SiC/SiC tubes for nuclear application

SiC/SiC composites are promising candidates for nuclear fuel cladding due to their outstanding mechanical resistance and properties at high temperatures (>1200°C). During the manufacturing process, a grinding phase of both the external and…

DVC Analyses to Study Deformation and Damage mechanisms of Teak in Torsion

Wood is a material with anisotropic elastic properties at the macroscale. In the present work, a sample made of Beninise teak was subjected to in situ torsion. DVC analyses were run at the mesoscale to measure displacement fields. The corresponding…

Probing Constitutive Models of Bohus Granite with In Situ Spherical Indentation and Digital Volume Correlation

Spherical indentation of granite was investigated using Digital Volume Correlation (DVC) aiming at probing constitutive laws of the studied rock. In situ indentation was performed within an X-ray tomograph. Finite element simulations of the problem,…

2D Numerical Simulation of Auxetic Metamaterials Based on Force and Deformation Consistency

This work showcases a novel phenomenological method to create predictive simulations of metallic lattice structures. The samples were manufactured via laser powder bed fusion (LPBF). Simulating LPBF-manufactured metamaterials accurately presents a…

Experimental study of corroded RC beams: dissipation and equivalent viscous damping ratio identification

Corrosion of steel reinforcement is one of the most common durability issues for reinforced concrete (RC) structures, especially when located in marine areas. The study of the mechanical consequences of this pathology is of great importance to…

Vers une stratégie robuste et automatisée pour le recalage de modèles en dynamique vibratoire : application au suivi des structures endommageantes testées sur table vibrante

Dans cette étude, la stratégie de recalage de modèle basée sur la minimisation de la fonctionnelle d’Erreur en Relation de Comportement modifiée est revisitée et automatisée pour des problèmes de dynamique vibratoire. Appliquée ici à des essais…
